3,180,026 HAIR THINNER ATTACHMENT HAVING CER- TAIN TEE'IH SPACE!) FROMTHE CUTTING EDGE F A BLADE .lohn DAmico, Little Silver, NJ. (136 Broadsi., Red Bank, NJ.) Filed Aug. 21, 1963, Ser. No. 303,555 2 Claims. (Cl.30-30) This invention relates to a hair thinner which is particularlyuseful to hair dressers.

The present invention is directed to the vprovision of a thinningattachment for a straight razor type Shaper which can easily be added tostandard single edge straight razors and is inexpensive to manufacture.The standard shaper straight edge razor performs no thinning function.However, it is utilized by a majority of the hair dressers in thecountry, and is thus widely accepted by the trade. The present inventionis directed to a hair thinner attachment which can be simply and easilyplaced over the standard straight edge razor type Shaper which willsafeguard the hairdresser against cutting himself or the customer whileinsuring a very satisfactory hair thinning operation. That is, the hairthinner of the present invention includes spaced teeth having free endportions extending from one side of the razor blade to the other whichteeth press down hair while allowing other hairs to pass therebetween tobe cut by the razor. Accordingly, the thinning function is achieved and,additionally, shaping is effected.

An object of the invention is the provision of a hair thinner which ismuch simpler and much less expensive than the well known thinningscissors.

A form of thinner herein disclosed is so constructed that the amount ofthinning per stroke of the device may be regulated or controlled, whichfeature the thinning scissors lacks.

The drawings illustrate the invention, and in these:

FIG. 1 is a front elevation of the device, comprising a razor and athinner attached to the blade;

FIG. 2 is a rear elevation of FIG. 1;

FIGS. 3 and 4 are respectively enlarged sections taken on lines 3 3 and4 4 of FIG. l;

FIG. 5 is a front elevation of a regulator used, in a modiiication ofthe device shown in FIGS. 1-4, to regulate or change the amount of haircut per stroke, and also shows the relation of the razor blade thereto;

FIG. 6 is an enlarged View of the right side of FIG. 5;

FIG. 7 is a front elevation of the thinner used in the modified form,and shows its relation to the blade;

FIG. 8 is an enlarged view of the right end of FIG. 7;

FIG. 9 is a front elevation of the blade, the thinner and the regulatorin combination, in which position the regulator is shown out ofregistration with the thinner, to reduce the amount of hair cut perstroke; and

FIGS. 10 and 11 are respectively enlarged sections on lines 10-10 and11-11 of FIG. 9.

Referring to the drawings for a detailed description, and at lirst toFIGS. 1-4, the numeral 15 indicates a razor comprising a blade holder 16holding a single edged replaceable blade 17.

A thinner 21, in the form of a comb, has end teeth 22 and teeth 22Aintermediate the end teeth. The thinner is mainly on one side of theblade, but the lower portion of each tooth is bent around the cuttingedge of the blade to the other side, so that the free ends of the endteeth 22 (FIG. 3) press against the blade to hold the thinner to theblade. The free ends of the intermediate teeth 22A do not press againstthe blade, as not being necessary, but they may be so bent if desired.

Referring to FIGS. 511 for a description of a modified 3,180,026Patented Apr. 27, 1965 form of the invention, `which includes aregulator or controller to change the amount of hair cut per stroke, inthis form a thinner 27 (FIGS. 7, 10, 11) has end teeth 28 andintermediate teeth 28A. The lower parts of all the teeth bend around theblade 17 from one side to the other, around the cutting edge. The endteeth 2S are pressed against the blade (FIG. 10) to hold the thinner tothe blade, but the intermediate teeth do not press against the blade.The end teeth 2S are shorter than the intermediate teeth 28A, therebyproviding space between the blade ICC . edge and the bends of theintermediate teeth. Such space is needed to accommodate the lowerportion of a regulator 31. The regulator is in the form of a comb and issimilar to the thinner 27, but is shorter, and its main portion isdisposed between and in contact with the thinner and the blade (FIGS. 10and 11). The regulator has spaced similar teeth 33 of the same width asthe teeth of the thinner 27, and the teeth interspaces are of the samewidth as the teeth interspaces of the thinner so that the teeth andinterspaces of both may be in registration. The teeth 33 of theregulator, however, are shorter than those of the thinner (FIGS. 10 and11), this being necessary because the bent portions of the regulator areinside those of the thinner.

The regulator 31 is connected to the thinner 27 so that it may beshifted lengthwise relative to the latter, which connection is made by ahorizontal bead 36 on the back of the regulator iitting into ahorizontal groove 37 formed on the front face of the thinner.

For the greatest thinning of the hair per stroke, the teeth andinterspaces of the thinner and regulator are put into registration oralignment by shifting the regulator. For a lesser thinning, theregulator is shifted to the desired extent, so that its teeth diminishthe exposed cutting edges of the blade.

It has been shown that the thinner may be attached to the blade byhaving teeth of the thinner press against the blade, in which case theholding teeth have their upturned free ends normally pressing againsttheir respective opposing parts of the teeth, the insertion of the bladetherebetween slightly separating the contacting parts of the teeth, thelatter being resilient. Any other suitable means may be used to hold thethinner to the blade, as for example the two triangular parts 40 (FIG.l) of the thinner, which parts are bent around the ends of the bladefrom back to front, at the inner ends of horizontal slots 41 formed inthe ends of the blade.

It has been found that the present thinner, when used with a wave motionon wet hair, promotes a wave therein, which cannot be done with athinning scissors.

What is claimed is:

1. A thinner attachment for a straight edge razor comprising a flatelongated main body adapted to be placed in juxtaposition to the razorblade, said flat main body having a height slightly less than the heightof the razor blade, spaced parallel teeth integral with said main bodyand having free end portions, said spaced teeth extending along a lowerelongated edge of said main body adapted to be placed adjacent the edgeof said razor blade, said teeth being bent slightly less than so thatsaid free end portions face said main body, said thinner attachmentbeing manufactured of a material having resilient qualities whereby saidblade can be placed between said free end portions and said main bodyand said thinner will be be held in place on said razor blade by reasonof the pressure exerted against the faces of the blade by the resilientteeth of the thinner, at least one tooth on each end of said thinnerhaving a height less than the height of the remaining teeth and beingadapted to touch the cutting edge of the blade whereby the remainingteeth will be spaced from the cutting edge of the blade.

2. A thinner attachment for a straight edge razor comprising a flatelongated main body adapted to be placed in juxtaposition to the razorblade, said flat main body having spaced teeth the free end portions ofwhich are adapted to extend from one side of the razor blade to theother, bent around the cutting edge thereof, a regulator slidablyconnected to the thinner, said regulator comprising a series of spacedteeth the free end portions of which are adapted to extend from oneyface of the blade to the other around the cutting edge thereof, theteeth and the teeth interspaces of the regulator being adapted torespectively register with the teeth and teeth interspaces of thethinner, and the regulator being adapted to be moved relative to thethinner so that the teeth interspaces of the thinner and regulator rnaybe only partially in registration.
